PyVisa with Keithley 2182A

I'm currently looking into reading in the voltage data over a set period of time from my Keithley using PyVisa but as of now I can only read in data one channel at a time, and I would like to be able to do both simultaneously.

Currently I choose channel 1, configure my buffer, and configure my timed trigger, then acquire channel 1 data for however long I set it for. Then I have to clear and reconfigure my buffer then gather the data on channel 2. 

If anyone could advise me on how to combine channel 1 and 2 during the first acquisition that would be a great help!
 

I believe the Model 2182A has only one A/D converter. Therefore, true simultaneous measurements are not possible. One channel needs to be selected and then a reading is taken. Then switch to the next channel and take another reading.

Best regards,
